Deepening Internal Mass Integration in Design of Reactive Distillation Columns, 1: Principle and Procedure

Abstract: For a reactive distillation column involving reactions with negligible or no thermal effect, the thermodynamic efficiency can be improved substantially through deepening internal mass integration between the reaction operation and the separation operation involved. Four strategies, including the superimposition of reactive section onto rectifying and stripping sections, relocation of feed stages, and redistribution of catalyst within the reactive section, can be used to intensify the internal mass integration.… Show more

“…Since the relative volatilities of the hypothetical reacting components are such that the reactants A and B are the light and heaviest components and the products C and D the lightest and heavy ones, the reactive distillation columns to be designed belong to the category of systems separating the RM-SURRV. The steady-state models of these processes are described in Appendix A and similar first-principle models can also be found, elsewhere (Huang et al, 2006Sun et al, 2009). …”

“…As shown in Figure , we recently proposed a reactive distillation column with a top–bottom external recycle (RDC-TBER), which featured transferring one of the unconverted reactants from one end where it accumulated to the other end where the reactive section was located. , In terms of the thermodynamic characteristics of the reaction operation involved (i.e., exothermic or endothermic), the reactive section should be arranged either at the bottom (Figure a) or at the top (Figure b), with the external recycle directed from the top to bottom or inversely. The external linkage between the top and bottom helps to boost reaction conversion rate and enhances internal mass integration and/or internal energy integration between the reaction operation and the separation operation involved. Therefore a significant improvement in system performance can be expected. So far, the RDC-TBER has already been evaluated intensively in terms of the separations of various ternary or quaternary reacting mixtures with the most unfavorable ranking of relative volatilities.…”
